Wei Ying-chiao, chairman of Taiwan's Ting Hsin Group, came in second on the list of the richest non-mainlanders in China with a net worth of 45 billion yuan, said the report, which was released by the China-based Hurun Research Institute.

Want Want's investment in China includes food and dairy products, as well as media, real estate and hospitals, while Ting Hsin invests in food, retail and real estate, it added.

The report said that if Tsai and Wei were mainlanders, they would have been listed in the top 10 of China's 100 richest individuals.

Of the 51 people on the richest non-mainlander list, Taiwan topped the list with 26 individuals, followed by Hong Kong and the United States.

The total net worth of the 51 people reached 318.5 billion yuan, up 5 percent from last year's list, according to the report.

The report added that Shanghai is the favorite location for non-mainlanders to set up business headquarters, while Guangdong and Zhejiang are the top choices for Chinese businessmen.
